Your furnace or AC filter in Portland helps to purify your air, which keeps bacteria, mold spores, and dust out of your lungs. It can’t do this when it’s already filled to the brim with contaminants, so it needs to be cleaned or changed on a regular basis . Watch this video for tips on how often you should change your HVAC filter.
If you find yourself coughing up pet hair and dander, or you notice that your allergies have been bothering you lately, these might be signs that you should change your HVAC filter.
